With the significant advances in additive manufacturing (AM), otherwise known as 3D printing, Orano Federal Services and the University of North Carolina at Charlotte recently re-examined the capabilities to print impact limiters for transportation casks used to ship spent nuclear fuel. Impact limiters protect transportation casks (sometimes also referred to as transportation overpacks) and their contents during an accident. Impact limiter designs must withstand testing based on a certain significance level of hypothetical accidents, including drops, crushing, fires, and immersion in water.

Pfluger

Levin

Rep. Mike Levin (D., Calif.) and Rep. August Pfluger (R., Texas) are urging Energy Secretary Chris Wright to establish a safe, effective, and long-term management program for spent nuclear fuel. In a January 15 letter to Wright, the two U.S. representatives asked the DOE to “break the current impasse over nuclear waste and develop a workable solution that encourages state collaboration.”

The letter was sent ahead of the DOE’s anticipated release of a new report that will recommend an updated national policy on spent nuclear fuel, as directed in Executive Order 14302, “Reinvigorating the Nuclear Industrial Base.”

The OECD Nuclear Energy Agency has issued a report calling for more-detailed information on tracking the decay heat of spent nuclear fuel from light water reactors. According to the NEA, the report highlights the increasing importance of accurate decay heat estimations due to evolving fuel characteristics, including higher initial fuel enrichment, increased burn-up rates, and extended reactor cycle lengths.

The report, Summary of the NEA Assessment on Spent Nuclear Fuel Decay Heat for Light Water Reactors, summarizes the findings of a subgroup of the NEA’s Working Party on Nuclear Criticality Safety (WPNCS), which ran from January 2022 to January 2024.

The Nuclear Regulatory Commission is asking for presentation proposals for a virtual workshop on the storage and transportation of TRISO and metal spent nuclear fuels for advanced reactor designs now under development.

The American Nuclear Society brought together 11 other energy and environmental advocacy organizations in calling on Congress to fund the Environmental Protection Agency to develop a new, technology-neutral, generic environmental standard for the disposal of spent nuclear fuel and high-level radioactive waste in the United States.

In a letter to the leaders of the House and Senate appropriations committees, the groups ask for an additional $3 million in fiscal year 2025 for the EPA’s Office of Radiation and Indoor Air to work on the new standard.

The Department of Energy’s Office of Nuclear Energy announced last week that the Association of American Railroads has certified its Atlas railcar system to operate on all major freight railroads in the United States.

Canada’s Nuclear Waste Management Organization, a not-for-profit organization responsible for the long-term management of the country’s intermediate- and high-level radioactive waste, is set to select a site for a deep geologic repository by the end of the year.

The American Nuclear Society coordinated an effort with eight nongovernmental organizations in asking Congress to update the Environmental Protection Agency’s generic standards for the safe, permanent disposal of spent nuclear fuel (SNF) and high-level radioactive waste.

The Department of Energy’s Office of Nuclear Energy has wrapped up testing of its Atlas railcar, successfully completing a round-trip journey from Pueblo, Colo., to Scoville, Idaho. Built to safety standards set by the Association of American Railroads (AAR), the 12-axle railcar is designed to transport large containers of spent nuclear fuel and high-level radioactive waste.

The Nuclear Waste Technical Review Board, which evaluates the Department of Energy’s activities on radioactive waste management, is holding a hybrid (in person and virtual) public meeting on August 30 to discuss the DOE’s consent-based process for siting one or more federal interim storage facilities for commercial spent nuclear fuel. The DOE’s research and development related to high-burnup SNF and advanced reactor waste disposal will also be discussed.

When it comes to managing nuclear waste, technology is transforming the way some of the most problematic waste is handled. The idea to transform nuclear waste into glass was developed back in the 1970s as a way to lock away the waste’s radioactive elements and prevent them from escaping. For more than 40 years, vitrification has been used for the immobilization of high-level radioactive waste in many countries around the world, including the United States.

While still lacking a deep geological repository for the permanent disposal of its commercial used nuclear fuel and high-level radioactive waste, the United States does have regulatory standards for geological nuclear waste disposal.

Having been written nearly 40 years ago, however, those standards are outmoded and lack transparency, according to a special committee of the American Nuclear Society, which has released draft recommendations on revising public health and safety standards for future geological repository projects in the United States.

Last fall, scientists from Sandia, Los Alamos, and Lawrence Berkeley national laboratories began the third phase of a years-long experiment to understand how salt and very salty water behave near hot nuclear waste containers in a salt-bed repository. Initiated in 2017, the Brine Availability Test in Salt (BATS) project is part of a spent nuclear fuel research campaign within the Department of Energy’s Office of Nuclear Energy (DOE-NE).

Issa

Levin

Reps. Mike Levin (D., Calif.) and Darrell Issa (R., Calif.) have reintroduced bipartisan legislation that would make the San Onofre nuclear power plant in Southern California one of the highest priority sites in the United States for the removal of spent nuclear fuel. The bill is being cosponsored by Reps. Scott Peters (D., Calif.), Michelle Steel (R., Calif.), Katie Porter (D., Calif.), and Young Kim (R., Calif.).

The Spent Fuel Prioritization Act would amend the Nuclear Waste Policy Act to require the Department of Energy to prioritize spent fuel removal from decommissioned reactors based on the size of the population near the plant, the seismic hazard associated with the area, and any national security concerns. The bill does not call for a permanent repository or consolidated interim storage, nor does it authorize the transfer of spent fuel to any non-consenting state or locality.

The Nuclear Regulatory Commission will continue work on a new rule on security requirements for independent spent fuel storage installations (ISFSIs), with two of the agency’s three commissioners voting to disapprove a request by NRC staff to discontinue the proposed rulemaking. The commissioners’ votes on the request were recorded on August 4, 2021, but were not made public until January 24.

The Department of Energy has issued a request for proposals for the fabrication and testing of a prototype eight-axle railcar to carry the nation’s spent nuclear fuel and high-level radioactive waste. The heavy-duty, flat-deck railcar design known as “Fortis” received approval from the Association of American Railroads (AAR) in January 2021 to proceed to building and testing.

Markey

Levin

Sen. Edward J. Markey (D., Mass.) and Rep. Mike Levin (D., Calif.) have introduced the Nuclear Waste Task Force Act. The legislation is intended to establish a new task force to consider the implications of amending the Atomic Energy Act of 1954 to remove exemptions from environmental laws for nuclear waste. Eliminating this loophole could help enable consent-based siting of long-term storage solutions for spent nuclear fuel and high-level radioactive waste, the lawmakers said.

Intended to continue the work of 2012's Blue Ribbon Commission on America’s Nuclear Future, the task force would also be responsible for providing a clear explanation of what constitutes “consent-based siting.”

As a knowledge manager for the 2018 Utility Working Conference, I had many opportunities to interact with nuclear utility leaders. The discussions often centered around finding innovative ways to sustain the existing fleet of nuclear plants by improving plant economics.

Levin

Davis

Hoping to drive progress on the safe storage, transportation, and disposal of spent nuclear fuel across the country, Reps. Mike Levin (D., Calif.) and Rodney Davis (R., Ill.) have formed the Spent Nuclear Fuel Solutions Caucus in the U.S. House of Representatives.

According to Levin and Davis, the bipartisan caucus seeks to address the challenges associated with stranded commercial spent fuel across the country and serve as a forum where House members can come together to make headway on the issue, regardless of whether or not they have a preferred solution.

In announcing the formation of the caucus on July 21, Levin and Davis said that the current system of spent nuclear fuel storage is not sustainable, particularly for sites that no longer have operating reactors and could be redeveloped for other beneficial uses. They added that it is also a violation of the promise, codified by law, that the federal government would take title to the waste in return for ratepayers’ contributions to the Nuclear Waste Fund.

The Nuclear Regulatory Commission plans to complete its safety review of Holtec International’s proposed HI-STORE consolidated interim storage facility by January 2022. A final licensing decision on the facility will be made in conjunction with the release of the agency’s final safety evaluation report, the NRC said in a July 2 letter to Holtec.
